As shown in the drawings, 2f) designates the base of the machine formed with a central raised portion, 21 a standard fixed in the seid raised port-ion of the hase, and 22 a sleeve surrounding the standard and rotative thereon. 23 designates the main driving shaft of the machine mounted in said base and a sleeve on the upper end of a standard Q4 rising from the base. Said shaft carries at its inner end a pinion 25 meshing with a gear wheel Q6 that is non-rotatively fixed to the lower end of the sleeve 22. 28 designates a liquid receptacle supported on said rotative sleeve. It comprises a bottom Wall 29 and inner and outer cylindric Walls 30` and 3.1, between which latter is formed an annular liquid receptacle 32 which opens upwardly. The liquid receptacle is mounted on said rotative sleeve through the medium of a pla-tc 33 fixed to the bottom of the receptacle and provided with a central cylindrlc sleeve or boss that surrounds .said sleeve. The said reservoir is locked to the sleeve by means of upper and lower locking nuts 35, 36:, respectively, interiorly screwthreaded to emga e exterior screw-threads on the sleeve an adapted to bear against the upper and lower ends, respectively, of said boss. This construction is provided in order to enable the reservoir to be raised and 1 22 to rotate with the reservoir and uon which the receptacles tojoe filled are de ivered from a horizontal feed table 41 suitably supported at the level of the carrier.

`The 'carrier embodies a plurality of gageplates 43 which rotate with the carrier and u on which the receptacles to be filled are directly delivered. The said reservoir is `atesa carrier beneath the reser- `voir Whic is mounted on the rotative sleeve provided with a plurality of valved feeding devices, designated as a whole by 44, in Figs. 1 and 2, and shown in detail in Figs. 6 to 11, inclusive, and the gage-plates 43 are located one beneath each valved feeding device and hold the receptacles in proper position beneath the feedincr devices while said receptacles are bein lld. The receptacles are adapted to be fed either automatically 10 or otherwise to the ga e-plates and after assin beneath the mac iiie are discharged om t e gage-plates upon the table 41, as herein shown.

The gage-plates are mounted on the upper ends of vertically movable lift rods 45 which extend through suitable openings in All'xticarrier plate 4() and have guiding enfagement with guide-sleeves 46 depending lfrom the carrier plate (Figs. 1 and 13). The said lift-rods are provided at their lower ends with rollers 47 which ride upon the upper edge of an annular cam track 48 supported on arms 49 of the frame of the machine in the manner shown in Figs. 1 and 3. The upper or active margin of said cam track embraces a lower part a (Fig. 1) which is located under the mechanism for feeding the receptacles to the carrier, whereby the gage-plates are in their lowermost positions when the receptacles are fed thereon, .an ascending part al, and a higher art a2. The engagement of the bearing ro ers 47 with the ascending part of the cam operates during the rotation of the carrier to raise the receptacles in position to receive the liquid from the feeding devices, and the engagement of the rollers 47 with the higher part of the cam track maintains the gageplates and the receptacles thereon in their uppermost or filling positions. As herein shown said age-plates are made se arate from the li t-rc'ds 45. Said lift-ros are provided at their upper ends` with heads 50 (Figs. 13 and 14) having lateral projections 51 extending radially inwardly over the carrier-plate and normally occupyin suitabl shaped o enings in the upper ace of sai plate. luide lugs 52 extend downwardly from said projections and have guiding engagement with the inner ends of said openings. The ga eplates are provided with Shanks 53 whic extend outwardly over the lateral projections 51 of the heads, and the parts are fastened together by screwstuds 54 extending upwardly through apertures in said Shanks and nuts 55 engaging in said screw-studs. Preferably also centering pins 56 are provided on the lower faces of the gagelates which enter o en: ings 57 in the hea s of saidlift-rods. .he ga -plates are provided with flaring side walls or flan es 58 so arranged as to center the receptac es on the gage-plates and t o provide wide mouths or approaches to facili- 66 tate the reception of the receptacles thereon .tei'chanveably use and their discharge therefrom. The provision of the removable gage-plates enables gage-plates of va ing dimensions to be in- Idyon the machine, whereby the mac ine may be adjusted to fill receptacles of varying shapes and diameters.

The rece tacles to be filled are fed from the feed ta le 41 to the gage-plates on the carrier by means of a rotary feedin device designated in Figs. 1 and 2 as 60, an shown 75 in detail in Fig. 4. It is provided with a plurality of vertically se arated radial, arms 61 and is located on the flied table at the side of the carrier in such position that the arms extend over the carrier in a manner to transfer receptacles brought into the influence of the arms from the feed table to the gageplates. Said rotary feeding device, as herein shown, com rises upper and lower plates 62, 62, spaced by a spacing sleeve 63 and is fixed to the upper end of a shaft 64 that is mounted in a vertical sleeve 65 depending from the feed table.

The empty receptacles are delivered into the path of the radial arms of the rotary feeding device through a vertical chute 67, which conveniently extends upwardly into a room above that in which the machine is located so that the receptacles are fed downwardly by gravity through said chute as the lowermost receptacle is transferred from the table to the carrier. The said feeding device is partially inclosed by a housin 68, the upper wall of which supportsthe feed chute 67. For rotating said feeding device the lower end ofthe shaft 64 is provided with a star-wheel 70 (Figs. 1, 3 .and 4) which is located in such relation to the guide-sleeves 46 of the lift-rods of the carrier as to be rotated in a step by vstep manner by engagement of said sleeves with the teeth or projections of said star-wheel.

The filled rece tacles are removed from the gage-plates o the carrier by meansof stripper bars 72 fixed to the -feed plate 41, 110 in the manner shown in Figs. 1 and 2. Said bars are curved at their inner ends and extend inwardly over said gage-plates to a point beyond the receptac es mounted on the gage-plates. Therefore, when the receptacles are brought against the curved ends of the stripper bars, through rotation of the carrier, they are forced out of the wide or flaring sides of the gage-plates upon the table 41, as shown in Fig. 2.

Referring now to the construction and arrangement of the filling devices whereby the liquid is dischar ed from the reservoir 28 into the receptac es on the carrier beneath the reservoir, and to the means for raising 125 the empty receptacles towards the filling devices and lowering the filled receptacles therefrom preparatory to discharging the receptacles om the machine, these parts are made as follows: It will be understood that 13o :its filling position (Fig. 7). provide when the rollers 47 of the gage-plate liftrods are riding on the lowermost part a of the cam track 48, the age-plates are in the plane of the feed tab and, therefore, in position to receive the receptacles. The ascending part al of said cam track acts through the lift-rods to lift the receptacles into the position shown in the left-hand side of Fig. 1, and shovvnv also in Figs. 7 and 13, which is the position the receptacles occupy While being fi led. All of the filling devices are alike and in the following detail description but one will be referred to. Each of said fillinfr devices comprises a tube 80 which |entends through a suitable opening in the lower Wall of the reservoir, and is supported on said Wall by means providing a fluidti ht joint, as shown in Figs. 6 and 7. Said tu is open at its upper end and is provided at its lower end, beneath the reservoir, vvith a conical discharge nipple 81 adapted to project into a central opening in the receptacle when said receptacle is lifted into adjacent to the bottom of the res- 'ervoir with an opening 82 through which the fluid is discharged from the reservoir into the tube and thence to the receptacle below. 83 designates a conical valve contained Within the tube and the conical nipple 81, and it serves When seated to cut off the flow of liquid through said nipple. Said valve is mounted on the lower end of a stem 84 by means of a flexible joint and the stem rises upwardly through the open end of the filling tube and is connected at its upper end with means for raising the valve from its seat, as will hereinafter be described.` Said stem is provided with radial guides 85 which hold the same centrally in the tube. Associated with Said filling tube is an air vent tube 80, which. as herein shown, is contained within the filling tube and extends above the same. The lower end of said vent tube 86 communicates with a passage S7 in the conical discharge nipple 81 which opens downwardly, whereby air may be vented from the receptacle. The said filling tube carries at its lower end a sealing ring 90 made of rubber or like elastic material which surrounds the discharge nipple 81, and upwardly against which the top wall of the receptacle Surrounding the central or filling Aopening therein is tightly pressed when the receptacle'is raised to its elevated or filling position. Said sealing ring serves to prevent the admission of air to the receptacle around the filling tube, whereby. when the lower end of the nipple of the filling tube is sealed by the rise'of liquid above the lower end thereof, the flow of liquid to the can Will cease. As herein shown said packing ring is seated an annular groove in a ring 91 which surrounds and has screw-threaded Said tube is engagement With the lower end of the filling tube.

After a receptable has been elevated in the manner described and sealed by the sealing ring 90, it is vented through the vent tube 86. When the receptable is presented to the filling tube, the vent tube is closed by a valve or plug 94, preferably made of rubber or like yielding material, which, in the present construction, is mounted on a block 95 that has vertically sliding engagement With the upper end of the stem 84 of the valve 83. The means for lifting the plug 94 to ventI the receptacle is made as follows: 100 designates a vertically movable lifting bar located outside of the outer wall 31 of the reservoir and provided at its uppex end with a laterally extending arm 101 directed towards the block 95 and provided With a vertical member having a rib 109. that has sliding engagement With a vertical groove 103 in the adjacent side of the block 95. The said dep'en'ding part of the arm 101 is provided at its lower end with a laterally extending lug 104 that is adapted to engage the lower end of said block 05 in a manner to lift the same when the lift-bar is raised by the means pro, vided therefor. Said lift-bar extends through and has guiding engagement with apertured guide lu s 105, 105 extending laterally outwardly fl'om the outer Wall of the reservoir and are connected, as herein shown, by a bar 100 that is riveted to the outer Wall of the reservoir. The said lift-bar 100 is provided at its lower end with an arm 110 that extends toward the lower end of the filling tube. Said arm is forked and the fork members 111 thereof extend on opposite sides of said filling tube. The fork arm 110 is herein shown as madea part separate from the liftbar. It is provided with an opening through which the lift-bar extends and is attached to the bar by a set-screw 112. The members 111 of said arm 110 are curved in the inanner shown in Fig. 11 to correspond to the general curvature of the receptable which the machine is adapted to fill, as indicated in Fig. 10.' Said fork-arm normally occupies a position entirely below the filling tube, as shown in full lines vin Fig. The fork Inernliers are spread such distance apart that when raised they clear the ring 0l carrying the elastic sealing ring 90, but are engager4 by the upper end of the receptacle when the latter is raised to present the same to the lower end of the filling tube. The raising of the lift-bar in this manner moves the lifting lug 104: into contact with the block 95, as indicated by the first dotted line position in Fig. 6, and further raising of the lift-bar raises said block and lifts the plug 94 out of engagement with the vent-tube. as indicated by the second dotted line position in F1g 6. In the present construction, the raismg of the lift-bar by the lifted receptacle as the latter is raised against the sealing ring 90 does not raise the plug 94 out of engagement with the upper end of the vent-tube, but only raises the arm 110 to a height suflicient to bring a bearing roller 115, extendin laterally outwardly therefrom, in position for engagement with the entering end of a curved cam-track 11G, (Figs. 1 and 2). Said upper cam track consists of a curved bar less than a complete circle and is concentric with the axis of rotation of the carrier. It is supported, as herein shown, from the lower cam track through the medium of radial brackets 117 on said lower track and bars 118 fixed at their lower ends to said brackets ,and carrying at their upper ends said up er cam track (Figs. 1, 3 and 5). As the earing roller 115 of said lift-bar arm rides on the entering end of the cam-track 116 the bar is lifted to raise the block and lift the plug 94 out of engagement with the venting tube, as shown in the second dotted line osition in Fig. G, thus venting the latter an the receptacle below the same. The active parts of the cam track 116 comprise a lower part a3 (Fig. 1), an ascending part a4, and a higlher part a5. The passing of the bearing ro er 115 upon the lower part en3 efl'ects the venting of the vent-tube 86 in the manner referred to. As said bearing roller ridesupon the higher art a5 of said cam-track, the cam-bar an block 95 are further raised until said block is brought up a ainst a shoulder on the valve stem formed y a. collar 1:20 attached to the upper end of the valve stem, whereupon the valve 83 is raised ofl' its seat and opens communication from the reservoir, through the filling tube 80, to the receptacle below, (Fi 7).l Said parts remain in the positions re erred to during the rotation of the carrier until the bearing roller 115 passes off the descending portion e of the upper cam-track (Fig. 2). The

said lift-bar bearing roller however passes off the cam-track 116 prior to the lowering of the filled receptacle to its lowermost pos1- tion, or the position in which it is discharged from the machine. This is made clear from a comparison of Figs. 2 and 3 wherein aT (Fi 3) designates the descending portion of t e lower cam-track 48 which is in advance of the descending portion a, of the upper curved cam tra( 116. By reason of the fact that the rise of the liquid in the receptacle above the level of the filliiig tube nipple and vent tube seals said filling tube and the further fact that the valve is closed before the receptacle drops away from the sealing rin 90, the receptacle cannot become overlle and danger of wasting the liquid is thus avoided.

In `order to avoid tendency of the liquid clingin to the lower end of the vent tube when t e plug or valve 94 is lifted from the upper end of said vent tube, and thus prevent proper venting of the rece tacle, means are provided for momentarily owering the receptacle from the sealing ring 90 after the plug has been lifted from the vent tube. This is effected in the present instance by providing on the upper surface of the lower cam-track 48, below the lower portion as of the upper cam-track, a depression a. When the bearing roller of a lift-rod 45 75 passes over said depression a3 of the lower: cam-track, the receptacle supported thereon is momentarily lowered and as the vent tube is open at its upper end, any liquid clinging to the lower end of said vent .tube is free to drop therefrom. The receptacle is thereafter raised by the passing of the bearing roller 47 on the higher` part of the lower cam track before the valve 1s opened. This construction and arrangement is especially useful in gravity fillin machines wherein but a smal liquid hea is possible by reason of the construction.

It will be observed, by reference 11o Fig.

5, that the bars 118 which support the upper 90 cam-track from the lower cam-track have vertical adjustment in the brackets 117 thus providing for accurate adjustment of the upper to the lower cam-tracks. This result is effected in the present instance by making the brackets 117 hollow to receive the lower ends of the bars 118 and clamping said brackets in said bars.

Inthe operation of the machine the empty receptacles are fed successively to the ageplates 43 of the carrier, as the latter 1s rotated about its axis. As the bearing roller of each gage-plate lift-rod 45 strikes the ascending portion a1 of the cam-track the receptacle 1s brought with .its end wall up 105 against the sealing rin 90. At the same time the receptacle stri es the arm of the lift-bar l0() and raises the bearing roller thereof to the level of the entering end a of the upper cam-track. In the con- 110 tinued movement of the parts the roller bearing of the lift-rod 45 of said gageplate drops into the depression a? of the lower cani-track 48, thus momentarily lowering the receptacle from the sealing rin and per- 115 mittmg any liquid tending to c ing to the lower end of the vent tube, which latter tube is now open at both ends, to drip therefrom. The receptacle is again raised with its top end a ainst the sealing ring 90 as the bear- 120 ing ro ler of the lift-rod 45 rises out of the depression a, after which, in the continued rotation of the parts, the bearing roller 115 of the lift-bar arm rises to the higher part of the upper cam-track and opens the valve to perlnit the fiow of liquid from the reservoir to the receptacle` The Iiow continues until the lower ends of the filling tube nipple and vent tube are sealed by the rising of the liquid in the receptacle around the same. Thereafter, in the continued rotation of the carrier, the lift-bar 100 drops to its iowermost position, thus closing the valve and the vent-tube, which prevents further flow of liquid from the tube regardless of the sealing of the lower end thereof. Finally the gagelate and filled receptacle su ported thereon ro to the level at which tiey are discharged rom the carrier, which latter o eration 1s effected hy the stripper bars at e proper oint in the cycle of movement of the mac ine. y

The machine is adaptable for filling cans, bottles and the like with milk, filling canned meat and fruit cans with syrup and juices and other analogous purposes.l The flow of the li uid takes place entirely by gravity there being no force required to be exerted on the liquid-to force it through the filling devices into the receptacles.

By reason of the fact'that the liquid valve of each filling device is opened only vwhen a receptacle has been delivered to its correspending gage late and raised to its filling position, it wil be apparent that in case of failure to deliver a recept cle to a gagel'ate no o eration of the associated filling evice Wil occur, thus avoiding waste of liquid which would occur in alike situation if the filling valve be operated independently of the presence of a. receptacle on its associated ageplate.

he mac ineis simple and economical in co struction, is capable of great ca acity and may be operated automatically. feature which greatly commends the machine is the' ease by which the various parts, which have contact with the liquid, may b e taken apart for the purpose of cleaning the same. It will be observed in this connection that the vertical groove on the block 95 enga-ged by the' rib 102 of the lift-bar arm 101 extends to the top gid? said block, so that 'the block, together W i'. the valve and stern, may be removed fromflie filling tube, thus leaving the filling 'tube free to be cleaned by the insertion of a brush or like cleanin device therein. It will also be observe that, by reason of the closing of the vent tube by the valve or lug 94, such liquid as is contained in the oWer end of the tube will not dri therefrom after thefilled receptacle is owerecl therefrom, thus avoiding, not only Waste of the liquid, but also tendency to uncleanliness, due to dripping Huid in the art of the machine adjacent to the receptac e feeding mechanism.
